Hi all,

Please see attached CMakeLists and cpp file for minimal reproducible example. The throw seems to not always trigger (roughly 20-30% failure rate for me).

Compiler:

hoc$ clang --version
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin17.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

hoc$ system_profiler SPSoftwareDataType | grep Version
      System Version: macOS 10.13.3 (17D47)
      Kernel Version: Darwin 17.4.0
